Hi,
Please see my inline.
Thanks

Wow, that's great!
So to conclude, when adding a compute node we need to run the following
services:
openstack-nova-compute
openstack-nova-api
quantum-openvswitch-agent
Looking at the script I see it's not dealing with chkconfig so we must
do it manually.

Hello,
The quantum network side is not covered in
https://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL#Adding_a_Compute_Node
so I'm trying to clarify this.
On a second node I've followed the instructions in the wiki minus
the network obviously since I'm running quantum+openvswitch (hybrid).
I'm applying some of the instructions found here:
https://fedoraproject.org/wiki/QA:Testcase_Quantum_V2#Setup but when
I'm doing "quantum-server-setup --plugin openvswitch" it's asking me
to install mysql, the scripts should be modified to also ask if
there's a DB running elsewhere (i.e. on the controller).
You do not need to install and run the Quantum service again. This
only needs to be run once on a "controller node"
On the compute node you need only to run the Quantum agent. Please
note that there is a utility script that you can use:
quantum-node-setup
Thanks

Anyway, I let it do its thing, install mysql and setup nova.conf,
then modified nova.conf with the quantum section from the controller's
nova.conf. Now my question is - in this case quantum_admin_auth_url
and quantum_url on the node should they point to localhost or to the
controller's address?
I'm thinking quantum_admin_auth_url should point to the keystone
service on the controller's IP and quantum_url should be
http://localhost:9696/?
Additionally:
quantum.conf - qpid_hostname should point to the controller's IP
This is done by the abovementioned script
quantum/api-paste.ini - [filter:authtoken] auth_host should be the
controller
No need
quantum/l3_agent.ini - auth_url should point to the controller
No need - you only need one l3 agent
plugins/openvswitch/ovs_quantum_plugin.ini - sql_connection should
be using the controller's mysql server
This is tread by the script. Please note that there is no access from
the agent to the quantum database. This is done via the message
broker.
Let me know if any of that is wrong or I missed some other settings
that should be notified.
Regards,
Lucian
